Matrix PRASAR UCS System Manual 363
If you select Peer to Peer as the SIP Trunk Mode and you do not configure this table, incoming calls on this
SIP Trunk will be rejected.
If you select Proxy as the SIP Trunk Mode and you do not configure this table, incoming calls will be
allowed only from the Registrar Server Address or Outbound Proxy Address. All other calls on this SIP
Trunk will be rejected.
If you have selected SIP Trunk mode as Peer to Peer, configure the following.
• Allow from all IP Addresses: Enable this check box, if you want to allow incoming calls on this SIP
Trunk from all IP Addresses. Default: Disabled.
• Apply Digest Authentication: Enable this check box, if you want to allow incoming calls from callers
only after the callers have authenticated themselves (with their User ID and Password). If the caller
does not enter valid credentials in two attempts, the system will reject the call.
If you have enabled Allow from all IP Addresses check box, Apply Digest Authentication check box will
be enabled automatically. You must configure the Digest Authentication table.
To configure the table, click the Apply Digest Authentication link. For detailed instructions, see
“Digest Authentication”.
• Consider Peer to Peer Table for Trusted IP Address: Enable this check box, if you also want to
allow incoming calls from the domain names or IP Addresses configured in the Peer to Peer table.
Default: Enabled. To know more about Peer to Peer table, see “Peer-to-Peer Calling”.
If you have selected SIP Trunk mode as Proxy or Peer to Peer, configure the Trusted IP Address table.
The first entry in the table will display the Proxy/Registrar Server Address:Port or Outbound Proxy
Address: Port as configured for this SIP Trunk (applicable only for Proxy Mode). For the Index numbers 1
to 10,
• Enter the IP Address and the corresponding Port from which you want to allow incoming calls.
Do not configure the port, if you want to allow incoming calls from all the ports for a particular IP
Address.
• Click Submit.
